The
Art
of
Coding
is
about
balancing
UX,
performance,
and
resources
This
talk
does
not
cover
the
unlimited
benefits
of
coding
in
resource
management:
smart

What
is
the

carbon
footprint?

What
makes
the
ICT
footprint
Make
=
2/3
Making
a
device
emits
100x
GHG
than
its
use
More
energy

lifeDme
Run

Dispose
≈

Less Make è Less Impact !
BUT
Actually, desktop lifespan divided by 3 over the last 30
years !
Where is the catch ?
